If google needs quality sites and with quality contents so what happen to gaming sites which most gaming sites used plugins like arcade game sites, mini game site etc. So all of them using automatic plugins and automatic post so those sites don't have a quality contents right so what happen to them?
Well you have to work with what you have got. You mention that there are automated blog posts, there should be some control over the content of these posts so make sure it is quality content containing target keywords. Aside from that make sure all other onsite factors are as well optimised as possible and then just focus on the things you can control like the quality of inbound links. Good luck
